The search for lesser known and underutilized crops, many of which are potentially valuable as human and animal foods has been intensified to maintain a balance between population growth and agricultural productivity, particularly in the tropical and sub-tropical areas of the world. Tigernut (Cyperus esculentus) is an underutilized crop of the family Cyperaceae which produces rhizomes from the base and tubers that are somewhat spherical. Many authors have reported the nutritional value of tigernut. Tigernut produces high quality oil about 25.5% of its content and protein about 8% of the nut. The nut is high in oil content and the oil was implicated as lauric acid grade oil, non acidic stable and very low unsaturated. The nuts were valued for their nutritious starch content, dietary fibre and carbohydrate. The nut is also very rich in mineral content (Sodium, Calcium, Potassium, Magnessium, Zinc and traces of Copper. Its tubers are also said to be aphrodisiac, carminative, diuretic, emmanogogue, stimulant and tonic. Tigernut has also been reported to be used in the treatment of flatulence, indigestion, diarrhoea, dysentery and excessive thirst. In addition, tigernut has been demonstrated to contain higher essential amino acids than those proposed in the protein standard for satisfying adult needs. There is the need for increased utilization and awareness about its health benefits.
